QSi Holding Limited is a media technology company that is based in Hong Kong S.A.R. (with business registration number 39130949). The company emerged in 2008 as the result of a joint venture between Querendo Limited from Hong Kong and System Integration Air Traffic Management AB (also known as Si ATM) from Sweden.

Querendo was founded in Amsterdam in The Netherlands in 1999. The company initially developed software for various clients throughout the Netherlands. However, in 2007 the company relocated to Hong Kong and shifted its focus to the development of media solutions on the internet and in public information systems.

Si ATM was founded in Sweden in 1981 and is a renowned supplier of Air Traffic Management and Control systems. Their product portfolio consists of various operational products and simulation systems and they have several reference case installations at airports and air traffic control centers around the world.
